Improving Your E-mail Delivery

Whether your e-mail boxes are hosted in the Public Cloud or a dedicated environment, the ability to deliver your messages is very important and may be optimized by the hosting provider and their users working together.

Sender

• Check the sender’s name and e-mail address.
• Use identification protocols.
• The SENDER FROM setting needs to match the FROM in your headers.

Addresses

• Delete addresses that do not exist or are idle.
• Check for spelling errors in addresses.
• Avoid mass sending.
• Fill-in the e-mail addresses in the Cc (or Cci) fields rather than one after the other in the To field for a mail shot.

Content

• Avoid:
  • HTML,
  • using too much punctuation in succession,
  • writing in red,
  • writing in block capitals,
  • using spam words.
• Pay attention to the e-mail subject.

E-mailing

Check that best practices are being followed by answering “yes” to the following questions:

• has the recipient expressly agreed to receive these emails?
• is there an unsubscribe link that is available, works and is easily identifiable?

Scoring system

To avoid misuse and optimize the deliverability of e-mails sent by its servers, alwaysdata has always implemented a scoring system based on various criteria like the content and frequency of the messages sent.

The lower the score, the better the e-mail will be rated and the sending accepted. In the Public Cloud, any e-mail with a score higher than 3 will be blocked. In Private Clouds, the default value is 5 and you can change it in the SMTP > Settings tab of your server. It cannot be disabled.

Based on this scoring, the message will be sent via an IP address with a more or less good reputation. This way, by optimizing the quality of your e-mails and their content, you will have a better chance of avoiding your message being considered undesirable.

This system uses Rspamd and a set of rules specific to alwaysdata.

In order not to be dependent on abuse from other users being the same mail server you can rent a dedicated IP in the Advanced > IP Addresses tab of the account. You will be asked to specify emails sent by this IP according to the rating they will have received by the antispam.

Notes

• The maximum size of e-mails sent is set at 50 Mbytes.
